The functions f(x) and g(x) are described using the following equation and table,
f(x) = -4(1.09)^x

a.

the y-intercepts for both functions are -4 so their y-intercepts are equal.

step-by-step explanation:

the y-intercept is when x is 0.

in the table x is 0 when g(x) (or y) is -4.

in the function, again the y-intercept is when x is 0 so replace x with 0:

so the y-intercept for f is -4.

both the table and function given has the same y-intercept.

x-4/x+7=f(-x)
